US Patent 11392612 Data processing method and device

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a data processing method are provided. One of the methods includes: distributing, to one or more computing devices, data of one or more leaf nodes in a blockchain node, for the one or more computing devices to compute checksums of the data of the leaf nodes; and determining, according to the checksums of the data of the leaf nodes, a root checksum of data in the blockchain node. Compared to conventional methods, these methods compute a checksum of data faster and more efficiently, and thus ensure proper generations of blocks and operations of a blockchain.
